4. ALWAYS maintain a suitable clearance between table and sanding belt.
5. ALWAYS hold the workpiece firmly so that it cannot be torn from your hands
6. ALWAYS ensure that nails or foreign objects have been removed from a
workpiece beforehand. Nails etc. will destroy the belt.
7. NEVER sand pieces which cannot be held firmly by hand.
GRINDING STONE SAFETY
1. Check the speed of the grindstone before fitting to your grinder. Never use
a stone with a rpm speed less than the rpm speed of your grinder.
2. The outside diameter and thickness of your accessories must be within the
capacity rating of the power tool. The correct size accessories can be
correctly guarded and controlled.
3. Never use a stone that is chipped, cracked or damaged. Fragments from
a broken or damaged grinding stone can cause serious injury. Make sure
that defective stones are destroyed and not used.
4. Bonded abrasive products are breakable and shall therefore be handled
with utmost care. The use of damaged or improperly mounted or used
abrasive products is dangerous and can cause serious injuries.
5. Always refer to the label for specified usage and observe the safety
information. Do not use for purposes other than specified.
6. Always use the correct stone for it’s intended task. Using the incorrect stone
can cause serious injury.
7. Allow the stone and tool to do the work. Never force the workpiece
against the stone as this could cause kickback and/or shatter the stone
causing serious injury.
8. Never use a damaged grinding stone. Inspect the stone before each use
for chips, cracks or excess wear. If the tool or accessory is dropped, inspect
for damage or install a new accessory. After fitting the accessory, position
yourself away from the plane of the rotating accessory and run the tool at
full speed. damaged stones may break apart during this test.
9. Abrasive products shall be handled and transported with care. Abrasive
products shall be stored in such a manner that they are not subjected to

USING THE MACHINE
WARNING: APPLYIING EXCESSIVE FORCE TO THE GRINDING WHEEL CAN
BE DANGEROUS AND COULD CAUSE DAMAGE TO THE MACHINE. NEVER
ATTEMPT TO USE THE SIDE OF THE GRINDING WHEEL.
USING THE GRINDING WHEEL
Although the unit is supplied assembled, there is a possibility that the guards
may have moved during transit. Check the guards, and make any
adjustments necessary before starting the motor.
1. Turn the gringing wheel by hand to ensure it is free, then switch ON by
pushing the switch so that the “I“ is depressed. To switch OFF push the
switch so that the “0” is depressed.
2. Allow the machine to reach full speed, then hold the tool firmly on the tool
rest and apply slight pressure on to the grinding wheel, allowing the grinder
to do the work.
NOTE: Never attempt to grind a piece of metal that is thinner than the
gap between the tool rest and the grinding wheel (1.6 mm).
USING THE SANDING BELT
1. Position the sander work rest as required (see fig. 4) and adjust as
described on page 12.
2. Switch the motor ON by pushing the switch so that the “I” is depressed, and
allow the machine to reach full speed. To switch the motor OFF push the
switch so that the “0” is depressed.
3. Hold the workpiece firmly on the work rest and apply slight pressure to the
sanding belt, allowing the machine to do the work.
WARNING: FRAGMENTS FROM A BROKEN/DETACHED GRINDING WHEEL
CAN CAUSE INJURY.
WARNING: ENSURE THAT THE WORKING POSITION ADOPTED DOES NOT
CAUSE OPERATOR FATIGUE WHICH MAY LEAD TO LOSS OF CONTROL OF
THE TOOL BEING GROUND.
WARNING: THE GRINDING WHEEL WILL CONTINUE TO ROTATE BRIEFLY
AFTER THE OFF SWITCH HAS BEEN PRESSED.
GENERAL USE
1. To start/stop the grinder, press the ON/OFF switch and start work.
2. Press the tool blade evenly onto the grinding stone and move the tool
sideways across the stone. Make sure that at least half the width of the tool
cutting edge comes into contact with the grinding stone at any time to
avoid damage to the stone.
3. Allow the machine to do the work. Do not apply excessive downward
pressure on the tool when grinding.
SETTING THE EYE SHIELD AND SPARK ARRESTER
Slacken the spark arrestor securing
screw and position the arrester so
that the recess is adjacent to the
wheel with a clearance of
approximately 1.6 mm, (as shown in
fig (5)). Tighten the screw to secure in
position.
The plastic eye shield, attached to
the spark arrester, should be tight
enough so that it does not move
under operational vibration, but
loose enough so that it may easily be positioned by hand.
SETTING THE TOOLREST
Slacken the two tool rest securing bolts and position the rest so that it is
adjacent to the grinding wheel with a clearance of approximately 1.6 mm, (as
shown in fig (6)). Tighten the two bolts to secure in position.
The clearance between the grinding
wheel and tool rest should be
maintained. If the clearance gap is
greater than the thickness of the
metal being ground there is a danger
that the force of grinding will cause
the work piece to be pulled into the
gap with great force and is
potentially very dangerous. An
incorrect gap could also cause
“chatter” which could result in
damage to the wheel.
SETTING THE SANDER WORK REST
Slacken the knob that secures the
work rest in place and position the
rest so that it is adjacent to the belt
edge and at 90 degrees to the belts
surface with approximately 1.6 mm
clearance, as shown in fig (7). Tighten
the knob to secure in position.
• It is recommended that a set
square is used to set the 90
degree angle. This will ensure
an accurate square finish when
the workpiece is placed on the rest.
MAINTENANCE
GENERAL MAINTENANCE
Make sure that all components are tight and secure. Always have any
damaged or worn parts repaired or replaced by qualified service personnel.
Do not attempt to repair the bench grinder unless you are qualified to do so.
The drive motor and bearings are sealed units and require no regular
maintenance. Should you require assistance, contact your local Clarke
service agent.
The grinding stone will wear down with use and may well go out of true. Use a
dressing wheel or stone grader to correct the trueness and to remove worn,
glazed grains from the stone.
The stone will have a finite life expectancy, dependant upon the nature of the
work being done. Periodically, make a note of the wheel diameter and
replace your (150mm) dia wheel if it reduces to an little as (130mm) in
diameter.
WARNING: NEVER OPERATE THE GRINDING WHEEL WITHOUT THE GUARDS
FITTED IN POSITION.
To renew or change the grinding wheels, proceed as follows
1. Switch off and un-plug from power supply. Remove the grinding wheel
covers by unscrewing the nuts securing the three retaining screws.
2. Remove the spark arrester bracket and eye shield by unscrewing the single
mounting screw. Slacken the tool rest mounting bolts, and pull the bracket
away from the wheel.
3. Hold the sanding belt roller firmly to stop the shaft rotating and remove the
nut and flange holding the grinding wheel, remembering that the nut has a
LEFT HAND THREAD.
4. Remove the used wheel and replace with a new one, ensuring that:
• The paper blotters and flanges are in place either side of the wheel.
• You do not overtighten the wheel nut.
5. Refit the grinding wheel covers by using the nuts and the three retaining
screws. Re-adjust the tool rest and spark arrester brackets.
6. Switch the machine on and allow it to rotate freely for at least one minute.
New grinding stones are frequently not true or in time can become grooved,
glazed (built-up), out of round or otherwise mis-shapen. To correct these
defects, a grinding stone dresser is available from your Clarke dealer.
• ET125 Grinding Wheel Dresser - Part No:1700225
• Replacement Dresser Wheel - Part No:1700230
• ET154 ½ Carat Diamond Tip Wheel Dresser - part No:1700329
1. If the grinding stone is new, allow it to spin for a minute with no load. Check
that it is spinning straight and true. If not, it will require dressing before use.
2. Stand to the side of the stone and hold the dresser handle firmly. Place the
dresser on the tool support so that its wheels can move freely (i.e, the
exposed part of the wheel should be facing up). Run the stone and apply
the dresser to the surface of the stone.
CHANGING THE SANDING BELT
To renew or change the sanding belt, proceed as follows:
1. Unplug from the power supply. Remove the sander cover by unscrewing
the three securing screws.
2. Slacken the sander work rest securing knob, and pull the work rest away
from the belt.
3. Slacken the belt tensioning nut until the belt feels loose on the rollers.
4. Slacken the top roller securing knob, allowing the top roller to move slightly
off its axis as shown in fig 9a.
5. Slide the belt off and replace with a new one, ensuring it lies centrally on
the top and bottom rollers
6. Retighten the top roller securing knob till it becomes firm but NOT too tight.
7. Tighten the belt tension adjuster nut until it also becomes firm. DO NOT
overtighten. The belt should now be fairly taught and positioned centrally
on the rollers.
IMPORTANT: The belt needs just enough tension to ensure that it does not
slip on the rollers whilst under load, however too much tension will shorten
the working life of the belt and the machine.
8. Replace the sanding belt cover, then adjust and tighten the work rest.
9. Rotate the belt by hand whilst
screwing the Tracking Adjustment
screw in or out to ensure the belt
runs centrally on the rollers. Turn
the screw anticlockwise to move
the belt outwards (towards the
outer cover), or clockwise to
move inwards.
10. When satisfied, plug the machine
into the power supply and switch
ON. Make fine adjustments with
the Tracking Adjustment screw if necessary.
CLEANING & STORAGE
Clean the exterior of the machine if required using a mild detergent or mild
solvent. Never immerse the machine in water. To reduce any fire hazard, keep
any cooling vents clear. If not bolted to a workbench, store the grinder in a
clean, dry location, out of reach of children.
